- Eligible family members will be identified by the patient, with the criterion that the patient would want the family member involved in medical decision-making for the patient if he/she was not able. For the purpose of this study, "family member" is not confined to legal next-of-kin or immediate family member. Any family member, friend, or caregiver is eligible who is English-speaking and has no dementia or delirium limiting his/her ability to complete questionnaires.
